Original post

Have you ever wondered how many Microsoft Teams there are within your organization? Do you want to know if a specific Office 365 Group is enabled for Microsoft Teams or not?

The Get-Team cmdlet in the MicrosoftTeams PowerShell module only gets all the teams that you belong to.

In this post I will guide you how to retrieve all Microsoft Teams in your organization.

Requirements

• You need to be an Exchange Online administrator, or at least be assigned the View-Only Recipients or Mail Recipients role in Exchange Online.
  
• You need to have an active Microsoft Teams license assigned;
  
• You will need an active PowerShell connection to Exchange Online;
• You will need an active PowerShell connection to Microsoft Teams;
  • This requires the Microsoft Teams module installed.

How to

Download my Get-AllMicrosoftTeams.ps1 script from the TechNet Gallery, which outputs a list of all Office 365 Groups that are Teams enabled within your organization, whether or not you belong to it.

This script runs the Get-UnifiedGroup PowerShell cmdlet which is available in the ExchangeOnline module. Each Office 365 group retrieved will be checked with the Get-TeamChannel PowerShell cmdlet, available in the MicrosoftTeams module, whether or not the group is Teams-enabled.

When you meet the requirements, go ahead and run it!
